I can take an educated guess as to what is happening with your turn signals flashing when you hit the brakes after installing the Hopkins Plug-In Simple Vehicle Wiring Harness # HM11140595, and it is very likely a poor or loose ground connection.
This is definitely the most common cause for issues like this, so take extra care to ensure the ground wire is attached to a completely bare metal surface. I have also added a link below to a help article on 4-way troubleshooting which I do recommend taking a look at.
